To all whom it may concern:

Be it known that I, JOHN A. CRAIG, of the townof Columbia, in the county of Chicot 'and State of Arkansas, have invented a new and useful machine for burning and thereby destroying green grass, noxious Weeds, insects, and combustible obstructions growing and lying upon the iields lin or intended for cultivation; and I do hereby declare that the following is a full and clear description of theconstruction and operation of the sa1ne,'reference being made to the annexed drawing, making a part of this specification, in Which Letter O is a perspective or side View; P, a

op view; Q, a front end View, and R a section or internal View,

.By reference to said drawing the different members of all the Vparts will be understood as follows: A, rollediron Sledge; l, fire-box; 2, air-funnel; 3, air-barrel; l, small drum; 5, fan for forcing the air into the fire-box; 6, Wheel;

7, large or driving drum; S, levers playing in grooved stanchions 10 to slide up and down, allowing the wheels to eleva-te or depress with the' inequalities of the surface of the field; 9,

' strap connecting the driving and small drums;

10, groovedstanchions in which theleversV S play; '11', doublefstanchions for bearing of fan and small drum-axle andfulcrum of le' vers; 12, axle on which are fixed thesmall drum 'and fan; 13, axle on which the wheel and large drum. are tired.l y

This machine in ust be made of metal, en-V cepting the wheel and large drum ad-frame` in which they work; which may be4 made eitherof wood or metal. Itisintendedto be. drawn by horsepower. `The wheel, being in cont-act with' the ground, gives mot-ion to Ythe` fan, which drives a current of air into the lirebox, forcing the flame downward through grates to the ground, and may be passed be-b tween rows of cotton, corn, sugar-can e, dsc., the

` rows of plants bein g protected from 'the action: i

of the heat bythe runner/s of the sledge A.v

That I claim as my invention, and'desire to secure by LettersPatent, is-

The application to thesurface of the ground of flames for agricultural purposes, using for that purpose the above-'descri bed machine or any other substantially the same which will by heat produce the'intended effect.
